Custom Popup

DuanePfeiffer

Trying to figure out how to create a custom popup when user taps on a feature in the map.  In my v 100.x code, I created a PopupDefinition object and set its title and customDescription (html).  V200.x has no customDescription.  It appears that I could build a list of fields?, but it is read-only.  Some guidance would go a long way here please.

EDIT: To clarify, I want to limit the fields that are shown in the popup as well as add text that is not in the field data.

Thank you for your question!  The easiest way to display popups is to define them in your web map and consume them in your application.  The Swift Toolkit has a `PopupView` which does exactly that.  You can find it here. It uses the array of `PopupElement`s defined in the `PopupDefinition` (loaded from the web map) to display the feature information.  There is a popup example in the Toolkit's Example app that shows how it's used.

If you are not using a web map, you will need to create the `PopupElements` you need and add them to the `PopupDefinition`'s `element` property.  The following are the possible element types:

• TextPopupElement - displays text (including HTML strings)
• FieldsPopupElement - displays a list of field data
• AttachmentsPopupElement - displays feature attachments
• MediaPopupElememt - displays images and charts

There is one additional type, `ArcadePopupElement`, that is not displayed, but when evaluated creates one or more elements of the other types.

The `TextPopupElement` will take an HTML (or regular) string, and display it in the same way the the v100.x `customDescription` did.

Once you have the elements defined in the popup definition you can create a popup and use that with the Popup Toolkit component. You can also use the Popup view Toolkit code as a guide if you want to build your own popup view.

Feel free to reach out if you need more information.
