im not sure what you mean by menu inside of a menu, so let me try to word it a little better. Alright lets say theres that line graph of votes on my site and theres drop down menu right above it (i just looked it up & its actually called drop down list. My bad). Looks kind of like this, cept with different options & no submit button)
. The list options are 24 hrs, week, month, year, and all time. When the user selects a different time period, the graph shown currently is replaced with the graph of the time period the user chose. It is almost exactly like the stocks charts on yahoo finance (http://finance.yahoo.com/echarts?s=AAPL+Interactive#symbol=aapl;range=ytd;compare=;indicator=volume;charttype=area;crosshair=on;ohlcvalues=0;logscale=off;source=undefined;)
Except the only thing my site would have in common w/ the stock chart is that the 1D, 5D, YTD, 1M, 3M, etc buttons right below the graph are listed as options on a drop down list on my site. When you click on one of those buttons, the chart updates immediately without the whole page refreshing, and I was wondering if something similar was possible on HTML.
