I am using the category dropdown menu as described in the user guide to display a list of entries for a single weblog. Because I have multiple weblogs on my site, I would like to use this same method to choose a weblog first and then choose a category from that weblog to display a list of entries. An example showing both of the dropdowns might look like this test page.
Is it possible to use dropdowns to choose a weblog first and then a category from that weblog to display a list of entries?
