Minimal master page in SharePoint 2013:

Step1: Select “Design Manager” and click on “Edit Master pages”

 

Step2: Select “Create a minimal master page” and enter the minimal master page name “SampleMinimal” and click on “Ok” button.

 Step3: Open the minimal master page through SharePoint designer 2013 and add the below lines of code in “SampleMinimal.html”

Reason: “Design Manager” Bug in SharePoint 2013:

The actual issue is users are unable to create list/library after applying the minimal master page.

“But when we are trying to create a new Document-library or List using "add an app" link it always shows "loading...” as shown in image and never ends.

<div style="display: none;"> <!--SPM:<SharePoint:AjaxDelta id="DeltaPlaceHolderLeftNavBar" BlockElement="true" runat="server">--> <!--SPM:<asp:ContentPlaceHolder id="PlaceHolderLeftNavBar" runat="server">--> <!--SPM:</asp:ContentPlaceHolder>--> <!--SPM:</SharePoint:AjaxDelta>--> <!--SPM:<SharePoint:AjaxDelta id="DeltaPlaceHolderPageTitleInTitleArea" runat="server">--> <!--SPM:<asp:ContentPlaceHolder id="PlaceHolderPageTitleInTitleArea" runat="server">--> <!--SPM:</asp:ContentPlaceHolder>--> <!--SPM:</SharePoint:AjaxDelta>--> </div>

Step4: Publish the major of version to the “SampleMinimal” minimal master page.

Step5: Set this minimal master page as default master to the site.
