Updating symbology for web maps

After publishing with ArcGIS Pro, you can edit, change, and save web map symbology using the Symbology dialog box in Event Editor.

When publishing with ArcMap, check the Allow per request modification of layer order and symbology option before publishing to enable editing, changing, and saving the symbology in the map layers.

Map symbology can be saved if Portal for ArcGIS or ArcGIS Online security is configured with Event Editor.

   Hover over a web map thumbnail to view additional information, such as the web map summary, tags, and last updated date.

4. Click the Layers button .
5. Click a symbol next to the layer for which you want to change the symbology.

   The Symbology dialog box appears.

   If saving an existing web map that you own, the file will be updated. If you are not signed in as the owner of the currently loaded web map, or if you are pointing to a configuration file, you will always be prompted to save as a new web map. If saving a new web map, see the following section.

   A confirmation message appears at the lower right once the map is saved.

The new web map with edited symbology is saved in the respective organization’s portal and is given a new web map ID.
