Wix how to hide feature options (no subfeatures) - wix

Question

There is a similar question
Edit context menu (selectiontree) in customize dialog?
but the link in the accepted answer states:
"You cannot remove Entire feature will be installed on local hard drive from the options. It is displayed only when there are subfeatures and enables installation of the subfeatures as well as the feature itself as opposed from Will be installed on local hard drive which installs only the selected features and does not affect subfeatures."
However, I have no subfeatures. How to remove the Entire feature... option?
Here's the code below:

Answer 1

It looks Windows Installer always displays Entire feature will be installed on local hard drive item even if there are no subfeatures. At least this item was present in all the cases that I tested where there were no visible subfeatures. It could also depend on the version of Windows Installer, I tested in Windows 7 with all the latest updates.
I've always thought Windows Installer doesn't display Entire feature will be installed on local hard drive item for a feature which has no subfeatures. Latest tests proved I was wrong.

You need to add the UI type in order to have a different UI in the installer.
<?xml version="1.0" encoding="UTF-8"?>

<Component Id="TheApp" Guid="*" Directory="INSTALLFOLDER">

<Feature Id="PdfFeature" Title="The PDF file" Level="1">
<Component Id="ThePDF" Guid="*" Directory="INSTALLFOLDER">

</Component>
</Feature>
<UIRef Id="WixUI_Mondo"></UIRef>
</Product>
<Fragment>
<Directory Id="TARGETDIR" Name="SourceDir">
<Directory Id="ProgramFilesFolder">
<Directory Id="INSTALLFOLDER" Name="WixTestFeatureTree" />
</Directory>
</Directory>
</Fragment>
</Wix>
add <UIRef Id="WixUI_Mondo"></UIRef> , also add reference to WixUIExtension.dll
each feature has **Level**attribute, level=1 meaning the feature will be installed, if you change the level for 1000 for example the user can pick in the custom dialog weather he wants to install this feature or not
