Hi
Im not sure if these are related or indeed 2 questions

1) Is it possible to make a custom taxomony mandatory. For example I have a taxonomy called 'Genre' I want a selection to be mandatory (rather than having a default value)

2) Can I then limit the taxomony so they are only able to select say 3
.

So to create a post an author must select between 1 and 3 genres. They cannot select none or 4.
This would be for front end cred forms

Thanks

Hello,

Since the wordpress custom taxonomy are not mandatory in admin side, and there isn't any limitation for "must select between 1 and 3 genres", so there aren't both of built-in features within Toolset Form plugin.

I suggest you add feature requests for them:

As a workaround, you might consider custom codes, for example, when user submit the form, use filter hook "cred_form_validate" to trigger a PHP function:
https://toolset.com/documentation/programmer-reference/cred-api/#cred_form_validate

In this function do the custom validations as you want.

Thanks, out of interest could this be done using a checkbox or select field- ie limit the amount that a person could select.

I know wouldnt be a taxonomy, but just wondering

Unfortunately, there isn't such kind of feature within custom select field or checkboxes field too.

The custom select field of Types plugin is a single choice field, so you can not select 2 or 3 options with it,
and there isn't limitation option for custom checkboxes field(multiple choices), so you can choose 4 or more options too.

You might consider custom codes, you can also check it with our Toolset contractors:
