Is there a way to remove the braces from the front end output associated with DynamicModule? For instance:

DynamicModule[{x}, {Slider[Dynamic[x]], Dynamic[If[x>.5,a=1;,{}]]}]

This returns a slider with braces around it. Is there a way to avoid or remove the braces?

    $\begingroup$ Row@{Slider...? This is what you want? $\endgroup$ – Kuba Sep 19 '13 at 5:57
  • $\begingroup$ @Kuba: Yes! But can they also be eliminated from the Dynamic[If[...]]? $\endgroup$ – user8454 Sep 19 '13 at 6:01

    $\begingroup$ @user8454 does Dynamic[If[x > .5, a = 1;, Spacer[0]]] do what you want? $\endgroup$ – Mr.Wizard Sep 19 '13 at 6:02
  • $\begingroup$ Yes @Mr.Wizard! Sorry @Kuba! Thanks guys! $\endgroup$ – user8454 Sep 19 '13 at 6:03
  • $\begingroup$ @Kuba Do you care to post both parts as an answer? $\endgroup$ – Mr.Wizard Sep 19 '13 at 6:04

Quick fix to your code would be to add Row and Spacer[0].

DynamicModule[{x}, Row@{Slider[Dynamic[x]], Dynamic[If[x>.5,a=1;, Spacer[0]]]}]

Instead of Spacer[0] you can use empty string: "", or Invisible[""].

Those braces are in output because you put them there. To know more about organizing an output, take a look at documentation:

there are also interesting related Q&A-s here on Mathematica.SE, for example:
