I am creating a tag filter like the one on http://nines.org/tags
They have a vertical slider that filters (increases and decreases) the tags.
I have an ArrayCollection of tags, and I want the vertical slider value to dictate how many tags are shown in the textArea, just like the one in the example on the site. How do I do this?
Hmm.. okay, the Vertical Slider will have a "value" property to access the current value. So something like..
.. should get you the value.
Now depending on how your ArrayCollection is writing tags into a TextArea, I believe only a limited portion / subset of the ArrayCollection can be used to generate tags inside your TextArea.
.. In addition to my previous comment, you can use the filterFunction in the ArrayCollection to limit the number of items in the ArrayCollection to be rendered as tags.
