Remove braces, {}, from around DynamicModule output?

Question

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

a=0;
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?

@Kuba: Yes! But can they also be eliminated from the Dynamic[If[...]]? — user8454, Sep 19 '13 at 06:01
@user8454 does Dynamic[If[x > .5, a = 1;, Spacer[0]]] do what you want? — Mr.Wizard, Sep 19 '13 at 06:02
@Kuba Also include "" as an alternative to Spacer[0] if you will. I have at times found Spacer more robust so I tend to default to it, but I cannot at the moment remember where or why. — Mr.Wizard, Sep 19 '13 at 06:07

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

a=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:
