I have an embedded dropdown menu within a table column. When I click on the dropdown the menu appears for a split second and then instantly disappears before I can select anything. If I hold down the dropdown option it stays and gives me a chance to click an option, but as soon as it populates the table it disappears.

table on edit complete, although it's my understanding that this shouldn't matter for an embedded view

I wonder if the problem is being caused by the enableColumnSelection being set to False. Try setting it to "true" and see if that corrects the behavior:

That's a good guess but it didn't work.

I found the issue!  
 ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/3/6/36e2b34279fa077d1a99eeecfcdb665adfe8bfdf.png)  
I had allowEditOn single click, and for whatever reason that makes the dropdown disappear as soon as it opens. If I switch it to double click or long click it works how I would expect it to.

What's weird is that to open the dropdown it only takes a single click, but my other components it takes a double click.

Is it possible to change this setting based on the column so I can only apply the double click to the dropdown? Thanks!
