Basic Infos

Hardware

WiFimanager Branch/Release: Master 2.0.17

Esp32:

Hardware: m5coreink

Core Version: ?

Description

we would like to store the values from wifi-manager in an array and have them displayed on the captive website.

here is the code:
// new (&custom_field) WiFiManagerParameter("customfieldid", blinds[], "Custom Field Value", customFieldLength,"placeholder="Custom Field Placeholder"");
