@bind input element generator?

[dustyirwin]

Hi all,

Is there a way to iteratively generate Pluto @Bind input elements (Button, CheckBox, etc)?

I've looked around and can't find this issue addressed quite yet. If I've missed something please let me know.

For example, it would be nice to be able to do something like the following:

vec = [1,2,3]

md"""
join( [ "$(@Bind var$i CheckBox()" for i in vec ], " | ")
"""

to produce the markdown:

md"""
$(@Bind var1 CheckBox()) | $(@Bind var2 CheckBox()) | $(@Bind var3 CheckBox())
"""

...and have it actually interpolate into a cell correctly. Important to note that the length and contents of vec may vary (in a sensible way).

Trying this general approach hasn't been fruitful and I'm hoping there is a more workable / elegant approach? It also seems that the ability to programmatically create UI elements (generating a drop-down menu for each column in a dataframe, for example) would be a prerequisite towards #664.

Thanks for any help! :)
