[jQuery] Resizable only to specified width

[jQuery] Resizable only to specified width


Hello,
I would like to create a weekly calendar where people can select one
day, or more.
I would like it to work a bit like outlook.
So when someone selects a day, it should be possible to resize the
selection to include more days.
Problem is that the resize should "snap" to a day, so that it is not
possible that someone resizes to the middle of a day.
When I look at the draggable feature, it is possible to add a "grid"
option, but I didn't see it for resizables.
Is this possible with the jquery ui plugin or perhaps with another
plugin?
Thank you.
