Increase Dropdown/Search Limit for Field Maps Layer Filter

[BrettFrahm]

While testing Field Map Layer Filtering I noticed that if you use a field with a lot of unique values like an ID field, it does not seem to work as intended. I first tried searching for the ID then I tried scrolling, both attempts were unsuccessful(see images below). My best guess as to why it is not working, is that there is a hard limit to how many unique values there can be in the filter. If this is the case, I would like to request that the search in filter look beyond the limit of around 2800 unique values.

Attempt at searching for ID

Scrolled down as far as I could and it only went to around 2800 or so.

You’re right — Field Maps layer filters currently cap unique value loading (around 2,500–3,000). It’s a known limitation to optimize performance. As a workaround, try switching to a text-based ‘contains’ filter or pre-filter the dataset in ArcGIS Online/Pro using a view layer. Increasing the dropdown/search limit would definitely improve usability — worth submitting as an enhancement request to Esri Support.
