In XML layout files, what's the difference between "remove=true" and "display=false"?

Question

I'm in the process of setting up a theme and have hidden several default elements (breadcrumbs, for example).

Some guides recommend:

<referenceBlock name="breadcrumbs" remove="true" />

whereas others go with:

<referenceBlock name="breadcrumbs" display="false" />

As far as I can tell these do the exact same thing. Does anyone know if there's a difference?

Answer 1

Attribute : remove 
Value     : true/false

• Allows to remove or cancel the removal of the element. When a container is removed, its child elements are removed as well.
• The remove attribute is optional and its default value is false.
• This implementation allows you to cancel removal of a block or container in your layout by setting remove attribute value to true

<referenceBlock name="block.name" remove="true" />

Attribute : display
Value     : true/false

• Allows you to disable rendering of specific block or container with all its children (both set directly and by reference). The block's/container's and its children' respective PHP objects are still generated and available for manipulation.
• The display attribute is optional and its default value is true.
• You are always able to overwrite this value in your layout. In situation when remove value is true, the display attribute is ignored.

<referenceContainer name="container.name" display="false" />
