I've four dropdown and all should be disabled while the page is loading to prevent select in other list until the page is completly loaded.
The reazon is, the fist is a list of Regions, depend on the selection, the second list is filled with a countries, and depend on the selection, the third list is filled with a states, if the users selected your option correctly there is no problem, but if need to change the region, while the page is loading, (and the user don't give time to breathe) the countries and states contains the oldest items.
I was tried in onload event, in tags, after tag, after , after tags, to enable. But ever enable before is completly loaded.
please, es very important. if you can write directly to firstname.lastname@example.org
PD: sorry for my english but I speak, write, think, eat in spanish.
