In this tweak I will add a custom element that will allow me to easily add a code snippet needed for multiple placeholders. For more information regarding multiple placeholders please read this
blog post.
First locate the file
CMSFormControls\Layouts\PageLayoutCode.ascx.cs and add the following code in the specified lines:
Line 150:
drpElements.Items.Add(new ListItem(GetString("PageLayout.MultiplePlaceHolder"), "mpl"));
Line 177-179:
case 'mpl':
elem = '<cms:CMSContent runat=""server"" id=""cntContent"" PagePlaceholderID=""plcContent""><cc1:CMSWebPartZone ID=""zoneA"" runat=""server"" /></cms:CMSContent>';
break;
This should look similar to the following screen:
Next make sure to add the localization string in the UI Cultures module:
Key: PageLayout.MultiplePlaceHolder
Text: Multiple placeholders
View the result:
Enjoy :)
