Text box entry beside multiple choice response instead of below

Looks like you might be using Flat layout. rondev's code from this post is working on my end to do this. Try adding the below to the question's JavaScript:

Qualtrics.SurveyEngine.addOnReady(function()
{
	/*Place your JavaScript here to run when the page is fully displayed*/

jQuery("#"+this.questionId+" .TextEntryBox").each(function() { 
	var tb = jQuery(this); 
	tb.css({"float":"none","background-color":"white","width":"50%"});
	tb.prev("label").css("display","block").append(" ").append(tb); 
});

});

Or, The New Survey Taking Experience does this by default.

Thank you! This worked now. I had other code that was overriding this code.
