Hi, 

1) Create this static resource: popupCSS
  
.slds-modal__container{
    max-width: 70rem !important;
    width:80% !important;
}
2) Use this new static resource with <lng:require> at the beginning of your component
  
<aura:component controller="MyCrtrl"implements="force:lightningQuickAction,force:appHostable,force:hasRecordId,force:hasSObjectName">
   <ltng:require styles="{!$Resource.popupCSS}" />

Hi Alain,

Hi Harjinder,

You will not find documentation on these topics because you cannot change the default width (just the height) using the standard options of the quick action for a  Lighting component. It is impossible by default without this trick of CSS.

The tricks like this one with CSS are workarounds by reading the source code directly of the page with the developer tool of Chrome and the help of other developers in this forum or elsewhere.

Best regards
Alain

Hi Alain,

      I just set the width of modal window  based on the second option("2) Use this new static resource with ..."), but one problem is that the static resource affect the modal window's width of other actions. If you have any solution about this, please let me know, Thanks.


Best Regards,
