+---
+
+## Part Creation Form
+
+New parts can be created from the *Part Category* view, by pressing the *New Part* button:
+
+!!! info "Permissions"
+    If the user does not have "create" permission for the *Part* permission group, the *New Part* button will not be available.
+
+{% with id="new", url="part/new_part.png", descript="New Part" %}
+{% include "img.html" %}
+{% endwith %}
+
+
+A part creation form is opened as shown below:
+
+
+{% with id="newform", url="part/part_create_form.png", descript="New Part Form" %}
+{% include "img.html" %}
+{% endwith %}
+
+
+Fill out the required part parameters and then press *Submit* to create the new part. If there are any form errors, you must fix these before the form can be successfully submitted.
+
+Once the form is completed, the browser window is redirected to the new part detail page.
+
+### Initial Stock
+
+If the *Create Initial Stock* setting is enabled, then an extra section is available in the part creation form to create an initial quantity of stock for the newly created part:
+
+{% with id="setting", url="part/create_initial_stock_option.png", descript="Create stock option" %}
+{% include "img.html" %}
+{% endwith %}
+
+If this setting is enabled, the following elements are available in the form:
+
+{% with id="initial_stock", url="part/part_initial_stock.png", descript="Inital stock" %}
+{% include "img.html" %}
+{% endwith %}
+
+Checking the *Create Initial Stock* form input then allows the creation of an initial quantity of stock for the new part.
+
+
+### Supplier Options
+
+If the part is marked as *Purchaseable*, the form provides some extra options to initialize the new part with manufacturer and / or supplier information:
+
+
+{% with id="supplierinfo", url="part/part_create_supplier.png", descript="Add supplier information" %}
+{% include "img.html" %}
+{% endwith %}
+
+
+If the *Add Supplier Data* option is checked, then supplier part and manufacturer part information can be added to the newly created part:
+
+
+{% with id="suppliers", url="part/part_new_suppliers.png", descript="Part supplier information" %}
+{% include "img.html" %}
+{% endwith %}
