Currently I use the Pinboard theme with 2 sidebars. In each sidebar I place one kind of widget several times. The point is that 2 widgets of a row (1 of each sidebar) belong together regarding the content.
What I really want is that I could place the 2 different widgets (belonging together) side by side in one sidebar and repeat this for the others in the same sidebar. I found the extensible widgets plugin (http://wordpress.org/plugins/extensible-widgets/) but it isn't maintained anymore for 3 years. So I didn't install it. Furthermore, I found some discussions about solving similar problems with tables or with css anyhow.
For better understanding you can see my WP instance here: http://turbine.reimone.net/
My problem is that each widget in a "widget pair" must be configured. The first widget is an event widget which comes from the All-in-One Event Calendar by Timely plugin and the second widget just is a text widget containing simple html. A "widget pair" is meant to be 2 widgets belonging together by content. Both widgets of a pair should be aligned side by side in the layout. I hope that both upper edges (one of each widget) in a pair are on the same vertical level so that visitors can determine better which widgets belong together.
Can you help me to solve this?
