Dropdown - Other Option

Whe I use ‘Other’ to ‘true’ in a dropdown control, I see a button on the UI, I dont know why this is required, cant I edit the dropdown like a text box?

When I have two dropdowns, and I’ve a Custom Java Script on the first drop down to load values in the second drop down using the custom Java Script.

If I donot use ‘Other’ to true, I get an error that the dynamically populated values are invalid.

If I use ‘Other’ to true, I can use dynamically populated values, however I get a button ‘Other’, I cant even make this invisible, it stays like that on the screen and opens up a dialog.

I think you would be better off by changing the ‘Dropdown’ control to be a ‘Combobox’ control instead.
