When adding apps on SharePoint 2013, we can add apps from
our organization app catalog or the built-in apps like Tasks and Customs
Lists. This works well when using the
default master page. The app selection view looks as shown below:
When applying a custom master page, we usually tend to
remove some of the content containers (ContentPlaceHolder) that we may not
need. This can cause some side effects
on some of the SharePoint components that may depend on those containers. In
our case, we had removed one of the following items:
Server Side Markup
<asp:ContentPlaceHolder id="PlaceHolderPageTitleInTitleArea" runat="server" />
<asp:ContentPlaceHolder ID="PlaceHolderLeftNavBar" runat="server">
|
This created a JavaScript error which can be visible on the
JavaScript console of your browser. The
end result was that part of the view was not rendered.
As shown above, the Apps you can add section is no longer
visible. In some cases, the container declaration may exist, but it is set to Visible="False".
This can also cause the rendering problem.
Solution
To address this problem, we can add the tags on the master
page and test the rendering of the view. The next step is to address the layout
issues that this can cause on our custom master page. For that, we need to use
some CSS magic to remove any of the content that we do not want displayed on
our views. An approach is to override some
of the classes that are found on the inner child elements as that should not affect how the add an app section is rendered.
Hope this helps.
