Hello there again.
I was in the middle of trying to figure out how to build a form, consisting of checkboxes of my categories. A visitor could then check off the categories they would like posts from, then click submit and those posts would be shown. I would have sworn there was a way to form the URL to get them and that the form itself would just need to build the URL... but I don't see a way to do this, even with any available plugins.
[*]Category 1 [ ]Category 2 [*]Category 3
[*]Category 4 [ ]Category 5 [ ]Category 6
[ GO! ]
What would be an easy way to do this? This has to have been done before, no?
