Omit Fields without data from the Pop up Window on Online MapViewer

WFCAdmin — Mon, 17 Feb 2025 00:49:01 GMT

I am making an online experience and need help with Pop-ups

I have a point layer that contains my company's environmental DNA sample results. There are over 1000 data points, containing information on over 20 species. The point attributes include 46 fields.

When a point is selected in the map, I would like the viewer to only see those fields in the pop-up window that have data for that particular point, instead of having to scroll through 46 fields to find the pertinent DNA results.

For example,

For this point, I would like the following pop-up window to omit all the empty rows (red slashes).

Can someone help me with this appropriate arcade expression?

I prefer the default pop-up look. No fancy headings or color are needed.

If you could provide an example that would be great!

Here are a couple of the fields in my data set.

Chinook_Salmon_DNA_Detected_

NumPos_ChinookWells

Coho_Salmon_DNA_Detected_

NumPos_CohoWells

Bull_Trout_DNA_Detected_

NumPos_BullTWells

Thank you!!

@WFCAdmin -

Try this -

This also allows a provision to remove certain fields like "ObjectID" and other tracking fields.
An example below -

Thank you so much!!!

Sorry, I am a total novice with Arcade.

For the fields line, I bracket each field with ' ' and separate each field with a comma? Do I close out the fields row with anything special?

Here is an example

return {

type: 'BULL_DNA_Detected', 'Num_BULL_Wells', 'DOVN_DNA_Detected', 'Num_DOVN_Wells'

fieldInfos: fieldInfos,

attributes: attributeValues

};

The arcade code is fully dynamic. No need to mention what fields to output. The only time you might want to specify the fields is in

var excludeFields = ["OBJECTID", "EditDate"];

These fields will be removed regardless if they are null or not.

Awesome!

I am getting very close! Thank you gis_KIWI4!!

I am struggling with where to imbed the expression.

I notice that it will replicate the fields list filtered perfectly, omiting all the empty fields, but only if I add the expression after the fields list.

If I remove the fields list and only only include the expression then nothing will pop up.

To get this to work, I had to remove the field list, then add a new Arcade content and embed the code there.

Then it will draw the popup table correctly.

It does work!

It just takes about 1-2 minutes to load the popup.

It looks like it defaults to ordering the fields alphabetically. Is there any way to correct this?

Thank you again!

Also, if it were possible to have the resulting popups use the display name instead of the field name, that would be amazing!

I don't really see any difference in performance using this vs. the Field List but I only have 33 fields and 1100 features.

I'm pretty new to this kind of Arcade myself, but saw this post and had the need to incorporate it into some existing maps.

However, I do not see a way to have it non alphabetical. The script seems to be returning the Fields in the right order, but they get automagically re-ordered in the popup.

Hopefully @gis_KIWI4 or someone with a better understanding of this can figure out a way.

If I get a chance in the future, may dive into this more.

Here is the code to use display names -

Here you can see the Highlighted fields have had the Display Name (ignore the other fields).
The test layers has Display name and Field Name the same.

Thank you gis_KIWI4!

So here is the issue that I am having.

If I simply have my title and the arcade expression I get only the title in the pop-up.

If I have the title, the field list with all 46 fields checked on, and the arcade expression, I get the full list followed by the abbreviated list. The abbreviated list works perfectly this way always filtering out the empty fields, but it defeats the purpose because the pop-up is still clogged with a bunch of blank data to scroll through.

Any suggestions?

If on the other hand I add a fields list below the arcade expression I get

I am not sure why that is happening.

I only have the title and arcade expression and it works.

Do you have any attribute expressions that might be causing this iss

No.

Just to be 100% sure, is this what yours looks like?

Is there anything under the Attribute Expressions section:

WFCAdmin — Thu, 20 Feb 2025 19:28:56 GMT

Yeah, it's empty, no expressions saved there.

Its bizzar. The first time I load up the web map the popups work perfectly. Then, if I click on a second point - nothing, just the title pops up.

Even more weird. If I click on another layer in the layers pane, then click back on the layer with the pop-ups, the pop-up functions properly. If i stay selected on the pop-up layer and select another point, the popups stop functioning. But if I then select another layer in the layers pain, then select my pop up layer again it works again. Its like the popup window only functions the first time, then needs to be reset!

Hi gis_KIWI4,

I am following the advice you provided in this post to modifiy my pop up attribute tables. I copy and paste the script you shared and modified for excluded values. Unfortunately, when embedding the script in the map even the attributes that have values are omitted from the pop up table. Do you have any insights into this? Much appreciated!

Best,

A. Yeaton

I have had success with using Arcade to accomplish this, however I really wish Esri would release a native solution to hide null fields. Seems like a toggle option would be possible. This would keep all layer settings like field order, aliases, even display format without having to tweak through Arcade.
