If you are an InDesign (CC 2014) user planning to export a fixed-layout ePUB and you have footnotes in your document, you might be dissapointed to notice that there is no option to make these footnotes become popup notes using the ePUB3 standard epub:type.
In the export to ePUB(reflowable) options we can select the popup type, but not for the fixed layout. Your footnotes will remain exactly where they are – on the page. Dissapointing no?
InDesign will expect the footnotes to be in the same XHTML file where they are referenced. There are some settings in InDesign, but nothing will help us convert them to invisible notes that are only seen in a popup. Is there a solution while we wait for Adobe to release another version of InDesign?
