Hi, I want to select a date from a calender in my tool, but I think that it's not possible in the xml. I was looking for some examples with xml, javascript and jquery but I could not do what I wanted. My code is: <tool id="idPlot" name="Plot"> <command interpreter="bash">r_wrapper.sh $script_file</command> <inputs> <param name="arg1" type="text" value="" label="Data 1"/> <param name="arg2" type="text" value="" label="Data 2"/> </inputs> <configfiles> <configfile name="script_file"> pv1 = "$arg1" pv2 = "$arg2" pdf("${out_file1}") source("/home/ramao/Galaxy-ES/tools/my_tools/modelo.R") devname=dev.off() </configfile> </configfiles> <outputs> <data format="pdf" name="out_file1"/> </outputs> </tool> I want that when I click in the input area the tool, it shows a calender to me select the date. Is this possible? With javascript? Or what? Thanks
