For further detail, this is what we are looking to do:
On the main “tags” page, we want to have a row for “parent tags”, which are essentially tag categories that other tags fall under. In our example, Parent tags would include “Syllabus Material”, “Exams”, and “Case Study”.
When you click on the Parent tag, all of the corresponding “Child tags” show up, and can be sorted by Count or Name. Here, Syllabus Material is selected as the parent tag, and “Topic 2” is selected as the child tag. Once a child tag is selected, it shows up in the box above.
Step 1:
Multiple child tags can be selected from each parent tag. In step 2 (below), “Exam 20” (Child tag) is selected from the “Exams” (Parent tag) section. This then appears at the box at the top.
Step 2:
Similarly, “Case Study Topics 2” (Child tag) is selected, and shows up at the top.
Step 3:
Finally, clicking the “Go” button queries all of the threads that have the selected tag combinations.
Step 4:
Please let me know if this is doable. Thank you very much!
