Maybe this is more of a PDF question than a GIS question.
Today, I received a layered PDF map shown as a landscape A3, with a square map on the left, and with the map title, the legend, the scale, a tiny overview map etc. on the right-hand side. However, each legend item had two tick boxes beside it: one for switching on/off the symbols and one for switching on/off the labels. It also contained radio buttons to switch between various background maps. I thought this was really elegant, and would like to create something similar.
I know how to create a layered PDF in ArcGIS, and then go to the Layers toolbar in Adobe Reader to switch on/off layers in the map. However, I'd like to know how I can embed the layer control inside the map.
(Note: I am not looking on how to draw individual tick and radio boxes, as I feel it's done by some application (semi-)automatically)
