Do you mean that when you click the button you want it to open a different tab in the dashboard? If so then look at the ui\_control node. You can make the first button send a message to the control node telling it to open the new tab.

Did you look at the help text for the node? In particular it says  
" The default function is to change the currently displayed tab. `msg.payload` should either be an object of the form `{"tab":"my_tab_name"}` , or just be the **tab name** or **numeric index** (from 0) of the tab or link to be displayed."  
So if you put the name of the dashboard tab you want to open, or the index number of the tab, in msg.payload and send it to the control node then it should switch to that tab. To do that from a button set the text the button sends to the name (or number) of the tab you want it to show.
