How does the drop-down perform when you have hundreds of options in it?

[brianteeman]

Probably quite badly based on the previous performance issues with a chosen select

[andrepereiradasilva]

@chrisdavenport to be honest just tested with joomla sample data index (46 items in content maps) with no notice change in page speed rendering.

Will try to test tomorrow with more items.

[andrepereiradasilva]

just tested with a random generated 5000 items content map! 200ms difference. Also a bit of 100ms opening the filter. The search is instant. I'm simulating a huge 5000 content map tree...

I don't have a huge search index database to test more properly. @chrisdavenport do you have it?

[andrepereiradasilva]

we could also do as the frontend and add the same filters the frontend have, instead of a all in one content map filter. (types are already there, so author, category and language). But i'm not sure about this, because for what i understand the level 1 branches are dynamic.
