How to Set default Category

Hi Enereuwa,
this is now possible with version 1.1.

1. To select a taxonomy term in the select dropdown, you can use the “selected” parameter:
[select name="tax_input" taxonomy="city" selected=7]

2. If you want a submission to be assigned to one or more categories or any taxonomy terms the post type has, you can do the following:
[text name="tax_input" taxonomy="*taxonomy-name-here*" value=*term-ID-here*]
Example:
[text name="tax_input" taxonomy="category" value=11]

You can do that multiple times per term ID you’d like to add. The last example would output (and you could even use the html input instead of the shortcode):
<input type="hidden" name="tax_input[category][]" value="11" />

Hope that works –
Thank you for the post.

Yeah I got tangled up trying to update this – 1.1.0 should be good to go now. Please let me know if issues come up –

Thanks
