In this question the solution to make Manipulate's slider longer is to use ControlType->Slider with ImageSize option. But I need to also have it expandable so that I could view and enter the numeric value. I've tried setting ControlType->Manipulator, but for some reason ImageSize stops working in this case.

Here's an example code which works with ControlType->Slider:

Manipulate[Plot[Sin[a x], {x, -3, 3}, ImageSize -> 800, AspectRatio -> 0.2], {a, -10, 10, ControlType -> Slider, ImageSize -> 800}]

How do I make the manipulator longer but still retain the controls under + button?

Maybe I am missing something, but why use ControlType for? Is this what you mean?

Manipulate[ Plot[Sin[a x], {x, -3, 3}, ImageSize -> 600, AspectRatio -> 0.2], {a, -10, 10, Appearance -> "Labeled", ImageSize -> 600} ]

  • $\begingroup$ You seem to be using version 10. Maybe they've fixed it there, but your code doesn't work for me on version 9. And only specifying ControlType to Slider makes the size correct for me. $\endgroup$ Commented Nov 28, 2014 at 19:49
