 # HDRP custom Material Inspectors

 #### Implementing a foldout section
 
-By default, UI blocks are not nested in a foldout. The foldouts in other HDRP Material Inspectors use the `MaterialHeaderScope` class. This class specifies the name of the header and whether the section is expanded or not. For an example of how to implement a UI block in a foldout, see the following code sample:

-Note that to track whether the foldout is expanded or not, `MateralHeaderScope` uses an `ExpandableBit`. To assign the `ExpandableBit`, this UI block example has a constructor that takes an ExpandableBit as a parameter. Because Unity serializes the state of each foldout in Editor preferences, you should use the `User[0..19]` part of the ExpandableBit enum to avoid overlap with built-in reserved bits. For an example of how to do this, see the code sample in [Custom Lit Material Inspector](#custom-lit-material-inspector).

-The `ValidateMaterial` function is very important because it ensures that the Material uses the correct keyword setup. HDRP stores the Material state in the properties themselves, this function reads these properties and then sets up the shader keywords these properties require. For example, if you enable the `doubleSidedEnable` property on a Material, HDRP requires the `_DOUBLESIDED_ON` shader keyword otherwise the material does not work. `HDShaderUtils.ResetMaterialKeywords` enables/disables this shader keyword based on the value of the `doubleSidedEnable` property.
