Textarea

You can create an Textarea parameter type that will be displayed as a multi-line text input on the configuration page. This is particularly useful when you want to collect application specific input from the user. For example: TLS certificates, keys or other data which is best suited to be entered in a multi-line format.

Constructor

The constructor of Textarea parameter type takes 3 useful parameters:

• name - The name of the parameter
• value - The default value of the parameter (optional - can be set as empty string)
• placeholder - The placeholder which is displayed when the input is empty (optional - can be set as empty string)

NetWizardParameter nw_textarea(&NW, NW_TEXTAREA, "Name", "Value", "Placeholder");
