Hi

I am trying to understand how will this policy apply the classes. This policy is used for the image component in an area. What are the different cq: styles refering to?

Also what is the variable currentStyle.offCanvasDivCss refering to in the template?

<div class="${currentStyle.offCanvasDivCss}" data-sly-unwrap="${!currentStyle.offCanvasDivCss}">

Hi @anasustic 

Here are the detailed documentation about policies  -

1. https://experienceleague.adobe.com/docs/experience-manager-64/forms/administrator-help/work-with-document-security/creating-policies.html?lang=en
2. https://medium.com/adobetech/fantastic-aem-configurations-and-how-to-code-them-edb5663e983f

cq:style - https://experienceleague.adobe.com/docs/experience-manager-learn/sites/developing/style-system-technical-video-understand.html?lang=en

currentStyle - Access design_dialog(currentStyle) properties.

Global content (that is, component values that are common across multiple instances of the same template) are stored as "styles" and edited via a "design dialog".

They are stored as follows:

/etc/designs/<design>/jcr:content/<template>/<component>

So, for the component logo in the template homepage, using the default design:

  • currentStyle is /etc/designs/default/jcr:content/homepage/logo


Hope this helps you!

Regards,
Santosh

    Hi,

    You can check how to access design dialog (policy) values in model

    https://taylor.callsen.me/accessing-content-policies-from-aem-dialogs-and-components/

     

    The cq:style works at front end, basically it map the stored value with policy style

    https://experienceleague.adobe.com/docs/experience-manager-learn/getting-started-wknd-tutorial-develop/project-archetype/style-system.html?lang=en

     

    Policy - https://github.com/arunpatidar02/aemaacs-aemlab/blob/master/ui.content/src/main/content/jcr_root/conf/aemlab/settings/wcm/policies/.content.xml 

     

    Applied at - https://github.com/arunpatidar02/aemaacs-aemlab/blob/master/ui.content/src/main/content/jcr_root/content/aemlab/reference-content/button/.content.xml 

     

     

    but if you want to get this in model then you can use below code

    https://github.com/arunpatidar02/aem63app-repo/blob/86b4495e3275b9358439846b586f4cefd96ad1b1/java/HelloWorldModel.java

      Hi

      Will the class

      cq:styleDefaultClasses

      be applied to any component of type Image in my case?

      If I understand correctly the documentation is the 

      cq:styleGroups

      available for Editors when they want to style the image component themselves. Is that correct?
