Add custom field validation in Content Fragment Model / Content Fragment

Question

Hello,

We have a requirement where we need to add custom field validation when creating a content fragment (CF) using a custom content fragment model (CFM).

Currently when I create a CFM, I only see some limited option like can mark field as required or specify max char limit etc. But what if i need to create a custom date field called "Age" where I can specify Regex or logic that selected date can not be in past date etc, something like that...

I know we can create custom data types which I can use in my CFM but I dont see option to add validations on field link Regex, compare values, compare date value with current time etc.

We are in AEM 6.5.5.

@mayukh007,It is possible, I have provided a solution around over a week ago, please take a look here -> https://experienceleaguecommunities.adobe.com/t5/adobe-experience-manager/ootb-validation-options-for-content-fragment-model-data-type/qaq-p/393540/comment-id/84746#M84746}}In short, you can use JavaScript to append the "pattern" attribute to a given HTML element, from there it will enable HTML validation for the content fragment field itself. Your client library should have a clientlib category of "dam.cfm.authoring.v2", so when you are on the cfm authoring view, your code will be run.
