I used dhtmlxcombo with filtering mode, how it can be restricted that nothng is typed which is not in the options…???

I want to restrict user to use only the options with filtering mode enabled, so i cant use readonly mode, that will hinder filtering mode???



Unfortunately there is no such option supported.
You can attach onChange code and reject values, which not equal to any of existing options, but there is no way to limit filtering to automatically reject not-existing variations during filtering.
