Data Size affects UI Design
So my wp-category-manager plugin ran into a little bit of a problem recently. One of the installations (they shall remain nameless) using the plugin, had slightly more tags than I had ever expected there would be. Loading that many tags into a select box was definitely not going to be a feasible solution. Not only is it unusable (who is really going to go through that many tags in a drop down list?) but just the ajax load for the drop down was freezing up the browser.
The only way I know how to design a UI to deal with these many values to sift through, is to either paginate or provide search (preferably with autocompletion). Building a paginated drop down feels like a dumb idea, so when I get a chance I will look to update the WP Category Manager plugin with a search box and auto completion instead. I think it will be a nice usability improvement in the case where there are more than a few tags.
On a completely different note, I am no SEO wiz.. but if you have more than a few dozen tags.. you are probably doing it wrong….
