[Qgis-user] HELP unable to sort multiple attribute values within a field

[John Bryant]

Hi Kelly, one method to try is to use a "Rule-based" renderer with a
rule for each species, something like:

array_contains(string_to_array("type", '; '), 'Hyptis')

This expression pattern should also work (but you might get false positives
where one species name is a partial match for another):

"type" like '%Alligator Weed%'

Each category would include all the features that match the expression, so
some features would appear in more than one category.

John
