Can someone put me in the right direction ? <BR /><BR />Thanks a lot for your help.</DIV> Tue, 06 Dec 2022 12:43:59 GMT https://community.graphisoft.com/t5/Archicad-C-API/Tree-view-for-showing-category-s-parameters-attributes/m-p/278757#M4044 Anonymous 2022-12-06T12:43:59Z https://community.graphisoft.com/t5/Archicad-C-API/Tree-view-for-showing-category-s-parameters-attributes/m-p/307649#M4045 <P>You can use the <STRONG>Tree View</STRONG> dialog item types, using the following GRC items:</P><OL><LI>SingleSelTreeView</LI><LI>MultiSelTreeView</LI></OL> Tue, 28 Sep 2021 10:11:24 GMT https://community.graphisoft.com/t5/Archicad-C-API/Tree-view-for-showing-category-s-parameters-attributes/m-p/307649#M4045 dushyant 2021-09-28T10:11:24Z
