If you activate such functionality, only formats that match specific attributes of a frame or an article element, appear in the list of the available formats when you display it.

Matching of formats and text uses three methods:

•Article element type: To filter list of formats by article element type, assign a type to a format. In such case, the list of formats will contain formats with such type, and formats without any type. An example: you have only two body formats: the Body 10pt format, and the Body 11pt format. You assign the body type to both. All other formats are assigned to other types.

You can assign only one type to a format

If you need a format to serve 2 or more types, you need to duplicate it. See Copy/duplicate formats in EdAdmin4.

•Article element category: To filter list of formats by article element category, assign a category to a format. In such case, the list of formats will contain formats with such category, and formats without any category.

You can assign only one category to a format.

•Text geometry: To filter list of formats by frame height, specify in the format a range of depth (minimum and maximum depth. In such case, the list of formats of a frame with a given height, will contain only formats that are within range of heights, and formats without any range.  An example: the minimum depth assigned to a format is 100pt, and the maximum is 120pt. Your frame has the height between those values: the format will appear in the list when you attempt to assign it to that frame.

If you specify more than one filtering method, they narrow the results to the format that satisfy all specified filters.

For further details about format filtering, see Customize format defaults.

Avoid J format and other unassigned formats

As all unassigned formats appear by default in all lists of formats, you may want to avoid it. Just assign all those formats to a type that cannot be paginated, to a category you never use, and to the height = 0.1pt. Use the type and categories that you seldom or never use, such as smsBody or similar. This will be enough to ban them from the lists of frame types.
