The Domain panel shows a nested tree-view listing of SNOMED CT domains.

Scroll up and down the listing via the scroll-bar to the right of the Domain panel, move up and down the list via your keyboard :arrow-up: and :arrow-down: keys, or drag your cursor onto the desired Domain name until it is highlighted.

The domain names are active - pressing one will change the context of the Applicable Attributes panel to those matching the domain, and also expand the Domain Details sub-panel at the base of the Domain panel.

The Domain Details sub-panel can be toggled closed/open when a domain name is selected.

This presents details corresponding to the MRCM domain reference set fields for the selected domain:

When open, press :chevron-down: on the right of the sub-panel title bar to close the Domain Details sub-panel.

When closed, press :chevron-up: in the sub-panel title bar to open it.

The listed domains can be filtered by typing match text into the Filter Domains... text box above the list.

Matching begins as soon as the first character is entered, and progressively filters as further characters are entered.

|
| |

Domains can also be filtered by entering an SCTID into the Filter Domains... text box.

If the SCTID matches an MRCM domain then only that domain is presented (since its SCTID is an exact match).

If an entered SCTID does not match an MRCM domain then the domain list will be blank.

Clear the Filter Domains... box by deleting the text, or move the cursor to the far right of the text entry box to reveal an X button, then press the X button to clear the entire text and re-show all domains.

| |

Alternatively, press RESET to the right of the context and actions bar (upper right corner above the three main content panels).

Since this action button also clears other selections such as Attributes and Attribute Ranges, a pop-up panel is presented to confirm the request.

Press RESET in the confirmation panel to clear all three content panels back to their initial view state, or press CANCEL to return to the current view without clearing.
