I want a non-editable filterable combobox?

How do I do it?

I am using dhtmlXComboFromSelect and enableFilteringMode(true) but that makes combo box editable as well. I tried to set readonly(true) but then filtering mode does not work.

What is the desired behavior ?

Possibly the solution, that was provided by one of our customers, could solve the issue:
