Restrict tag field to max 2 tags TouchUI

[vjleo94]

I have a dialog field of following resource type 

sling:resourceType="cq/gui/components/coral/common/form/tagfield".

I would like to allow authors to select maximum of two tags. How to achieve this ?

Hi @vjleo94 

This blogpost might help. Have not tried this out myself.

@JeevanRaj I saw this as well. But this is being done on a tagpicker. Not on a "cq/gui/components/coral/common/form/tagfield"

We can implement custom validators.

Please check below example for validators.
