When displaying feature layers in a map or scene, you can identify attribute information about a feature without making a selection or interfering with an existing selection by opening a pop-up. Use the Explore tool 
to click a feature, or drag a box while pressing the Ctrl key to identify multiple features. The Pop-up pane displays a list of identified features, grouped by layer, and a formatted array of read-only field attributes.
The following are advantages to using pop-ups:
- Pop-ups can streamline your workflow if you want to see a limited list of attributes all the time.
- You can customize pop-up display to format the information in a stylized manner.
- You can pin a pop-up to the screen to compare features.
- When you create and customize pop-ups, they are honored when shared in web layers. Pop-ups configured through ArcGIS Online can be consumed in ArcGIS Pro and appear in the open map.
Note:
Multiple-column pop-ups are flattened into a single column when published to ArcGIS Online.
- Coordinates are displayed for individual features as you view their attributes. You can copy coordinates for use elsewhere.
- You can select or navigate to identified items from the results list.
- You can flash the identified feature. If the feature is small or it is difficult to locate the flash, turn on the Show crosshairs when flashing option on the Navigation tab of the Project options.
- You can place a point graphic at the center of the feature in a map from the tree portion of a pop-up.
- You can restart related record navigation by promoting a feature to the top of the results tree using the context menu.
- You can copy the records of a feature or a selection of features from the results list.
- You can print an image of the attribute portion of the pop-up.
Note:
Video content is not included when printing a pop-up.
- You can access and configure the display of related data.
Note:
The first 200 related records load automatically. To load any remaining, scroll down to the last related record and click the Load all... button.
- You can find out more information about route feature measurements.
- You can explore both the features and relationships in a knowledge graph.
- You can explore both the features and associates in a utility network.
Open a pop-up
Pop-up functionality is built into the Explore tool , the primary tool for common navigation commands. Click an identifiable feature using the Explore tool to automatically open the Pop-up pane. To open a pop-up for multiple features, press the Ctrl key and drag a box with the Explore tool. Layers that do not allow for pop-up customization, such as raster or LAS, do not support the ability to identify a multiple feature result.
The Pop-up pane appears as a floating pane by default and displays all identified results. Use the context menu for each identified feature for additional commands, including navigation options, selection, pinning the pop-up, removal, and opening layer properties. A pinned pop-up is for a single feature and is fixed in place. It does not disappear until you close it or return the pop-up back to the Pop-up pane and identify new features.
Note:
Pop-ups are associated with the map or scene where they originated. Changing focus to another map or scene causes them to disappear; however, open pop-ups reappear once focus is returned. If you float the map or move it to another monitor, the pop-up doesn't go with it.
The order in which pop-ups are presented depends on the Explore tool layer order options. You control this
ordering by selecting an option using the
drop-down arrow under the Explore tool on the Map tab. The following options are available:
- Topmost Layer—Only the topmost layer drawn on the map returns pop-ups.
- Visible Layer—Only layers currently visible return pop-ups.
- Selectable Layers—Only layers marked as selectable return pop-ups.
- Selected in Contents—Only layers currently selected in the Contents pane return pop-ups.
- No Pop-ups—No pop-ups are returned.
If you do not want pop-ups to appear for your layer, right-click the layer or select multiple layers in the Contents pane and click Disable Pop-ups 
. This removes the pop-up configuration for the current layer. Use the same context menu to re-enable the pop-ups. You cannot configure the appearance of a pop-up for a layer that has disabled pop-ups. Open the Configure Pop-ups pane for the layer containing the disabled pop-ups and click Enable to customize the content in your pop-up.
View data attributes in a pop-up
A pop-up is a read-only display of attribute information. It is a convenient way to identify feature attributes without requiring a feature selection first. Use the Attributes pane or a table view if you need to edit the attributes for selected features. The pop-up display contains a tree view listing of all items identified that are grouped by layer and the attributes of one feature at a time, which are separated by a gray divider that controls the pop-up orientation.
Results list
Expand the nodes of the tree view listing and click each identified item to view the individual attribute content. Individual features and groups also have a context menu for additional commands such as the following:
- Select, sort, or navigate to identified items.
- Flash the identified feature. If the feature is small or it is difficult to locate the flash, turn on the Show crosshairs when flashing option on the Navigation tab of the Project options.
- In a 2D map, place a point graphic at the center of the feature.
- Open the properties of the layer.
- Copy the records of a feature or a selection of features.
- Restart related record navigation by promoting a feature to the top of the results tree.
When an identified feature participates in a relate or relationship class, you can expand the nodes of the tree view to explore the related data. However, once the data exploration returns to the originally identified layer, that relate can no longer be expanded.
Note:
If the related data participates in an in-map relate and is removed from the Contents pane, the tree stops expanding at the related node.
Attribute display
The attribute portion is configurable to display custom text, field-value pairs, charts, images, and so on. Click an image, or press Enter while the image has focus, to view it at full resolution. Right-click an image to choose between opening the image in either the standard image viewer or the 360-degree image viewer. Alternatively, to open it in the 360-degree image viewer using only the keyboard, press Ctrl+Enter while the image has focus. You can also view related data by expanding the feature name in the listing portion of the pop-up. For related data that does not exist in the map, you see the default pop-up. For related data in your map, you see the pop-up definition that you authored. If the related data is in the map as a time-aware or range-aware layer, the list of related records is filtered based on the map's current time and range settings. You can click in the view to display pop-ups for feature, raster, LAS, and TIN layers, with or without a selection.
Change pop-up orientation
A pop-up is divided into two sections by a gray divider. You can use the divider to collapse one portion or change the pop-up from the default vertically stacked orientation to side by side. Hover over the gray divider to reveal buttons that allow for these actions.
To hide the tree view listing, hover over the gray divider bar and click the Hide Top button 
. The gray divider shifts to the top of the pop-up and the feature attributes expand to fill the pop-up. Alternatively, you can shift the divider to the bottom using the Hide Bottom button 
. This collapses the feature attributes, and the tree view listing of identified items fills the pop-up.
Click and drag the gray divider bar to change the size of each side as well as to reveal a hidden portion.
The Split Vertically button 
changes the orientation of the pop-up from vertically to horizontally stacked. If a portion was previously collapsed, it expands into view. Once in a side-by-side configuration, you can similarly collapse the right and left sides and return the orientation to vertically stacked.
Pin a pop-up
You can pin a pop-up for an individual feature to the screen so it does not disappear when you click a different one. This is helpful if you want a side-by-side feature pop-up comparison, or if you work with dual or large monitors and spread out your application display. You can pin more than one pop-up in a map. To pin a pop-up, right-click it in the Pop-up pane listing and click Move to Pinned Pop-up. The pop-up remains pinned until you either return it to the Pop-up pane using the Move to Pop-up Pane button on the pop-up banner or close the pop-up.
Note:
Any numeric or date formatting changes made while a pop-up is pinned will not be applied when the pop-up is returned.
Customize pop-ups
To build your own pop-ups for feature layers, right-click the layer in the Contents pane and click Configure Pop-ups 
. The Configure Pop-ups pane appears, where you can customize the appearance. You can do the following in the Configure Pop-ups pane:
- Define a title for the pop-up. The Display field is the default title.
- Add and configure media elements such as images, charts, and hyperlinks.
- Split elements vertically or horizontally to create a custom appearance.
- Insert a carousel item to display multiple element types in a series.
- Configure statistics for related data.
- Style and format properties for fonts and outline borders.
- Further enhance most elements using HTML.
- Show a list of attachments.
- Use Arcade expressions to allow for more formatting control.
- Disable the pop-up configuration for a layer so the pop-up does not appear.
- Swap element content or rearrange element order.
- Change the pop-up to appear in the classic mode.
Attachments
For layers with enabled attachments, you can display a list of attachments in a pop-up by enabling the Show list of Attachments option in the Configure Pop-ups pane. When a feature includes attachments and this option is enabled, a list of hyperlinks is displayed, ordered from oldest to newest, at the bottom of the pop-up. These links open the attachment in the default file handler. Features without attachments display a message indicating that there are no attachments.
You can also source an image using attachments. By default, all attachments that are of type=image are included in the pop-up. The most recently added image attachment appears first. Alternatively, you can show only the most recent attached image. Click an image to view it at full resolution.
Coordinate values
Feature coordinate values are displayed at the bottom of the pop-up window and can be selected to copy and paste into other applications. The values shown come from the geometry of the selected feature in the pop-up list. If your pop-up contains more than one identified feature, the coordinate value changes when you select a different feature in the list. The coordinates are not the clicked location on the map.
Tip:
To capture the coordinates of a clicked location, right-click that location and click Copy Coordinates 
. The current coordinates are copied to the clipboard. To use a different format, expand the Convert Coordinate submenu and click the desired final format.
The coordinates represent different spatial elements of the feature, depending on its geometry type. The following is a list of features and coordinate source returned:
- Point—The feature's point location
- Line—The feature's midpoint
- Polygon—The feature's centroid
- Multipatch—The feature's centroid
- Multipoint—The feature's centroid
- Annotation—The feature's centroid
- Dimensions—The feature's centroid
M-aware features
Some features contain measured values (m-values) in their geometries to support linear referencing workflows—for example, placing traffic accidents along a road or monitoring corrosion conditions along a pipeline. When linear features containing route measures are identified, six additional measurement fields are added to the Fields element of a pop-up. These are Measure, Minimum Measure, Maximum Measure, Measure Values, Parts, and All Measures Unknown. Because these are part of the Fields element, their formatting can be modified.
Note:
These six additional measurement fields may not appear in pop-ups when shared.
The coordinate display of m-aware features in the pop-up includes the m-value closest to the clicked location in the map or scene. For linear geometries, the value is calculated by interpolating between the nearest vertices. M-values only appear when the pop-up is accessed from a single clicked location. M-values do not appear when you access the pop-up from the table view or when you press Ctrl and drag a box to identify.
The m-value coordinate display uses the numeric formatting of the default distance units set for the project, including properties such as decimal places and padding with zeros. To configure the default distance units for your project, click Project, click Options, and choose Units. Click in the Format column to open the Numeric Format dialog box for the default unit.
You can use Arcade expressions to gather and manipulate m-value information for a feature. For example, the expression below converts the measure in minutes to hours and displays the maximum m-value in hours for the clicked feature.
var myLine = Geometry($feature);
var mMax = -1;
// If m-aware
if (myLine.hasM) {
var myArray = myLine.paths;
// For each path
for(var k in myArray) {
var myTmp = myArray[k];
// For each vertex
for(var p in myTmp) {
// Get the m-value
var myM = myArray[k][p].m;
// Update the max-M, if needed and divide by 60 minutes
if(mMax < myM) {
mMax = myM/60;
}
}
}
}
// If not m-aware
else {
mMax = -999;
}
// Return maximum m-value
return mMax;
