@brief Displays the input as a string.
@details Converting a combination of label + input + description, wrapped in a div, is a several step process.
First, we must use placeholders to hold the above elements during the wrapping and tabbing process.
Otherwise any tabs in the input / description / label will be modified, which breaks especially breaks textareas.
Then, after wrapping and retabbing is done, replace the unique placeholders with the actual elements.
@return string The input + label + description as a string.
