Remove Tag Helpers with @removeTagHelper

Remove Tag Helpers with @removeTagHelper

The @removeTagHelper removes a Tag Helper that was previously added by @addTagHelper.

It has the same two parameters as @addTagHelper:

@removeTagHelper *, MyApplicationTagHelpers

For example, when you want to restrict a specific Tag Helper on a particular view, you can apply the @removeTagHelper to remove the specified Tag Helper.

Using @removeTagHelper in a child folder's _ViewImports.cshtml file (e.g. Views/Folder/_ViewImports.cshtml), it removes the specified Tag Helper from all of the views in that Folder.

Opting out of individual Tags

Instead of removing the Tag Helper from a View, you can also disable a Tag Helper at the element level with the Tag Helper opt-out character ("!").

For example, we can disable the Email validation in the <span> with the Tag Helper opt-out character:

<!span asp-validation-for="Email" class="text-danger"></!span>

In this case, the Tag Helper will be disabled on a single element (<span> in this case), rather than all elements in a View.

The Tag Helper opt-out character must be applied to the both opening and closing tags.
