Hi ,team

I have a webdropdown on my form and enabled its multi-select property to select multiple text from a database,then insert the value of the selected webdropdown into a new field (called field "A") of another database(called databese "B").

My problem is I want to edit that field "A" the same way I insert it,with a webdropdown,I cannot read the field "A" data into the webdropdown.  Its just like the "Select Tags..." in this web site.

How can  I achieve this? please forgive my bad english, hope you can understand what I mean.

thanks in advance.
