Expand / Collapse a Folder
Users can expand or collapse a folder by clicking on the plus sign or negative sign next to the folder icon.
Expand (Open) a Folder: Click on the plus sign next to the folder in the Navigate Terms view. The folder will open and all the items in the folder will display.

Options
Users can define how many concepts to display and whether or not to show hidden terms and/or synonyms. The display options are set in the Navigate Terms Options dialog window, which can be accessed by clicking on the Show Options button.
Maximum to Display
The Maximum number of children to display is used when expanding a folder in the Navigate Terms view. Once the maximum number is reached a message will appear informing you that you have reached the maximum and continuing to retrieve all the concepts in the list may affect performance. You will have the option to continue or to cancel the action.
Show Hidden Terms
In the metadata table, an attribute is set to determine whether or not a term is active, inactive or hidden. If an item is marked as hidden it will not appear in the list of terms. Selecting Show Hidden Terms will display those items marked to be hidden. For easy identification, hidden terms will be red when displayed in the results list.
Show Synonymous Terms
Some terms may be flagged in the metadata table as a synonym of another term. Selecting Show Synonymous Terms will display both the original term and the synonym in the Find Terms view. For easy identification, synonymous terms will be blue when displayed in the results list.
Enable Patient Counts
The Enable patient counts option will display the total number of patients that have an observation fact entered for that item.
Use Short Tooltips
By default, the tooltip that displays when you hover over an item will contain the entire path name and the tooltip that is specific to that item. Enabling the Use short tooltips option will only display the tooltip information; the path will not be included.
Show Concept Codes in Tooltips
In addition to showing the tooltip, this option will also display the concept_cd associated to the item.
Disable Modifiers
The ability to search for modifiers will not be available if the Disable modifiers option is checked off.
