title: generate mulitple text boxes depending on drop down menu selection
body: <p>I want to have a drop down menu that selects either rgb or hsl  or the hex # code for the specific color they want, and a submit button that once the user selects their option and pushes submit, 3 text boxes appear for either the rgb or hsl option, or 1 text box for the hex#code to allow them to input the correct # for it to correlate to the color option they want. in the end, this assignment will display the color they chose to input, but for now, i just want to get the drop down menu and text bars working. how should I go about doing this? ive been trying to write code for it and I cant seem to get it. </p>
  
  <p>to summarize ==> select option:  |rgb, hsl, hex| ==> user pics one, and clicks submit. depending on if he choose rgb/hsl or hex, 3 input text boxes will appear or 1 box will appear. along with the boxes appearing will also appear another button called generate. so they can submit their input to display the color.</p>
