# Intro {% hint style="warning" %} The formbuilder requires a mouse or trackpad so touch device like iPads or Android tablets are not supported yet. We therefore recommend to build your form(s) on a desktop or laptop. A minimum screen width of **1024 px** is also required to be able to show all the user interface controls. {% endhint %} Currently, Epicollect5 allows a maximum of **300** questions per a single form, and a maximum number of **5** linked (hierarchy) forms. The form builder features a three columns layout: * Left column: the available inputs * Middle column: the inputs added to each form * Right column: the currently selected input settings ![](/files/FIrDWL1IvpaM3U32ZTnL) By default, each input is shown on a single screen on the mobile app. This allows space for the popup keyboard and the question at the same time. You might want to have more than one question on a page, in that case just use a [**group**](/formbuilder/groups.md). {% hint style="warning" %} Remember, **you cannot set jumps on inputs within a group**, just on the group input. [**More on jumps.**](/formbuilder/jumps.md) {% endhint %} ### Video Tutorials {% embed url="" %} {% embed url="" %} --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
