Webfig is it possible to make a selection box

This is what i’m trying to do, I want to setup webfig to be able to have selection box of predefined items for customer so that they don’t have to change anything by typing. Just have to select a pull down box and apply. So far I have not been able to do it. Would be nice if it could be done anywhere in the interface. Want to be able to have one for SSID and on another to be able to select the preferred source. But it would come in handy for lots of options.
