Hi, I've a project requirement (AEM 6.2) where I need to restrict the specific component in parsys to a limited count? Let's say I've 3 component allowed for a particular section parsys. Let's call it {A, B, C}. The 'A' component can be dragged any number of time in parsys but if component 'B' is dragged on parsys then it shouldn't allow to drag component 'C' and vice-versa. Thanks, Vijay

Here is the working example:- Experiencing Adobe Experience Manager - Day CQ: AEM 61 - Touch UI Limit the Number of Components Add...
But, Editable template has evolved big way now. I would recommend you to use Editable Template for this.

This is where when using a more recent version of AEM Editable Templates and policies are best practice. When setting policies in an editable template - you can control which components are allowed to be used.

Hi Rajashankar ,
Thanks for the reply . In the link you have provided , one with reply that is marked as correct seems like those urls are not valid any more.
thanks,
Vijay.

Hi vijayk87714775,
You will have to write a custom JQuery listener to handle this on the drag and drop event.

I fix follow these steps:
1. Login crx/de and create a custom js folder touchui-limit-parsys
ui.apps/src/main/content/jcr_root/apps/myapp/clientlibs/touchui-limit-parsys
2. add the categories and dependencies for the clientlib folder
categories="[cq.authoring.dialog,cq.compat.authoring.widgets,myapp.components]"
dependencies="underscore"
3. create file ui.apps/src/main/content/jcr_root/apps/myapp/clientlibs/touchui-limit-parsys/js/touchui-limit-parsys.js

4. create file ui.apps/src/main/content/jcr_root/apps/myapp/clientlibs/touchui-limit-parsys/js.txt
js/touchui-limit-parsys.js
5. set a limit on the policies
ui.content/src/main/content/jcr_root/conf/myapp/settings/wcm/policies/.content.xml
<testcomponent jcr:primaryType="nt:unstructured"> <testcomponent-style-system jcr:lastModified="{Date}2021-07-20T09:05:25.344+07:00" jcr:lastModifiedBy="admin" jcr:primaryType="nt:unstructured" jcr:title="Test Component Style System" sling:resourceType="wcm/core/components/policy/policy" acsComponentsLimit="2" autopauseDisabled="false" autoplay="false" components="[/apps/myapp/components/content/test1component]" delay="5000"> <jcr:content cq:lastReplicated="{Date}2021-03-08T06:29:29.280Z" cq:lastReplicatedBy="bmdesai" cq:lastReplicationAction="Activate" jcr:mixinTypes="[cq:ReplicationStatus]" jcr:primaryType="nt:unstructured"/> </contentsplit-style-system> </testcomponent>
Note: In the testcomponent we can add limit test1component by the config acsComponentsLimit="2"
