# Property Groups The Property Groups part of the Data Maintenance section allows users to create and edit property groups, define their display settings, and set their order on [material pages](/total-materia-integrator/total-viewer/material-pages/overview.md). Users can also configure main property groups and define child (subgroups) under them. Additionally, the system allows assigning colors to main property groups in order to improve their visibility and help users more easily distinguish them on [material pages](/total-materia-integrator/total-viewer/material-pages/overview.md). To create a new property group or edit/delete an existing one, simply click the

buttons in the interface. Clicking the "ADD PROPERTY GROUP"

button opens a new window in which users can either assign a child property group to an existing main property groups or define a main material group by clicking

slider to the right. {% hint style="warning" %} After adding the new property group, assign it to the appropriate [User Profile](/total-materia-integrator/creator/user-management/user-profile.md#property-groups) in "Property Groups" section to ensure its visibility. {% endhint %} "Property group" text box, in which the property group name is defined, is mandatory and must be populated when adding both parent and child property groups. To add a property subgroup (child group), the main property group must be selected in drop-down list.

"Enable condition filters" checkbox, when adding child group is optional. When and if selected, three additional checkboxes will appear, each used to control the display of filtering options on [material pages](/total-materia-integrator/total-viewer/material-pages/overview.md). When the checkbox "Show thermometer in filters" is selected, temperature ranges will be displayed. "Show references in filters" will enable the display of references, while "Show properties in filters" will enable showing and filtering propererties on material pages for defined property group.
