There are several types of input tags:

  </form>

text areas
On Xmosaic, the SIZE parameter is interpreted as a textarea. This is ignored in Mosaic for Windoze and proper TEXTAREAS should be used.

This wont work under Windoze


 

 ROWS=5 COLS=30 ALIGN=middle

This will work under Windoze




<TEXTAREA ROWS=5 COLS=30 ALIGN=middle>			This is a textarea

submission buttons




Type="submit"

reset button




 Type="reset"

check boxes

radio buttons

Hidden text useful when there are a sequence of forms, data from one can be hidden in input fields and shared across all the forms. Hidden fields should only be generated by a CGI script.

password box




 Type=password

This creates a pull-down menu containing Options in a form.

single select


  <form>

  <select NAME="direction">

  <OPTION SELECTED> North

	<OPTION> East

	<OPTION> South

	<OPTION> West

  </select>

</form>

multiple single (use ctrl-click to select)


  <form>

  <select NAME="direction" MULTIPLE >

  <OPTION SELECTED> North

	<OPTION> East

	<OPTION> South

	<OPTION> West

  </select>

</form>

produces:

This is probably the strangest tag. When I first saw it, I though that it provided a free text searching capability on a set of documents.

What it actually does is to provide a ready built form (standardization and all that), all you have to do is provide the processing at the server end.

Note: on Xmosaic the isindex form is in-lined, on MSwindows the form appears at the bottom of the screen... weird!!

This allows us to put a panel of text in a form

in Xmosaic, the text is shown within the text area.
