How i can hide "Content Type" drop-down from Edit list form, and show it inside Create list form

Question

I have the following inside my SharePoint 2013 on-premises.

1. Custom List inside my Team site.
2. Three Content Types inside the Custom List.

Now when i create a new item by clicking on the "new item" link :-

i will only get the fields for the defualt content type. while if i edit an existing item, i will get the "Content Type" drop-down list:-

so my questions are how i can do the following/if possible:-

1. Hide the "Content type" drop-down list from Edit form.
2. Show the "Content type" drop-down list inside the New form.

Thanks

Answer 1

You can use SPField.ShowInEditForm and SPField.ShowInNewForm

Show Hide columns using PowerShell

Answer 2

To hide the "Content type" drop-down list from Edit form, add a content editor web part in the Edit form, add the following code in it:

<script src="http://code.jquery.com/jquery-1.10.2.js" type="text/javascript"></script> 
<script type="text/javascript">
$(function() {
  $("select[id*='ContentTypeChoice']").closest('tr').hide(); 
}); 
</script>

As for show the "Content type" drop-down list inside the New form, unless you create your own URL to NewForm.aspx without parameters,the ContentTypeId is by default present as a QueryString parameter.

Each content type has its own newForm.aspx. When added to a list you choose which content type (which newForm.aspx) you want to use on the dropdown of the new button. By the time you get to the newForm.aspx you are already committed to a specific content type.

Answer 3

The simplest option is to use the New Item drop-down in the Ribbon...

For a new item, SharePoint determines the form to use based on a QueryString parameter that includes ContentTypeId. This prevents on the fly changes to the form once it is opened... See this question for more detail.

You could create a custom form to handle this situation (Nintex or something would really help here) but you would have to decide if it's worth the time.

If you want to hide drop down menu with content type, You can create custom control template for your list.

1. Add new control template to folder C:\Program Files\Common Files\microsoft shared\Web Server Extensions{current_version}\TEMPLATE\CONTROLTEMPLATES You can take default template from DefaultTemplates.ascx Template for list:

     <SharePoint:RenderingTemplate id="ListForm" runat="server">
        <Template>
            <table>
                <tr>
                    <td>
                        <span id='part1'>
                            <SharePoint:InformationBar runat="server"/>
                            <div id="listFormToolBarTop">
                            <wssuc:ToolBar CssClass="ms-formtoolbar" id="toolBarTbltop" RightButtonSeparator="&amp;#160;" runat="server">
                                    <Template_RightButtons>
                                        <SharePoint:NextPageButton runat="server"/>
                                        <SharePoint:SaveButton runat="server"/>
                                        <SharePoint:GoBackButton runat="server"/>
                                    </Template_RightButtons>
                            </wssuc:ToolBar>
                            </div>
                            <SharePoint:FormToolBar runat="server"/>
                            <SharePoint:ItemValidationFailedMessage runat="server"/>
                            <table class="ms-formtable" style="margin-top: 8px;" border="0" cellpadding="0" cellspacing="0" width="100%">
                            <SharePoint:ChangeContentType runat="server"/>
                            <SharePoint:FolderFormFields runat="server"/>
                            <SharePoint:ListFieldIterator runat="server"/>
                            <SharePoint:ApprovalStatus runat="server"/>
                            <SharePoint:FormComponent TemplateName="AttachmentRows" ComponentRequiresPostback="false" runat="server"/>
                            </table>
                            <table cellpadding="0" cellspacing="0" width="100%" style="padding-top: 7px"><tr><td width="100%">
                            <SharePoint:ItemHiddenVersion runat="server"/>
                            <SharePoint:ParentInformationField runat="server"/>
                            <SharePoint:InitContentType runat="server"/>
                            <wssuc:ToolBar CssClass="ms-formtoolbar" id="toolBarTbl" RightButtonSeparator="&amp;#160;" runat="server">
                                    <Template_Buttons>
                                        <SharePoint:CreatedModifiedInfo runat="server"/>
                                    </Template_Buttons>
                                    <Template_RightButtons>
                                        <SharePoint:SaveButton runat="server"/>
                                        <SharePoint:GoBackButton runat="server"/>
                                    </Template_RightButtons>
                            </wssuc:ToolBar>
                            </td></tr></table>
                        </span>
                    </td>
                    <td valign="top">
                        <SharePoint:DelegateControl runat="server" ControlId="RelatedItemsPlaceHolder"/>
                    </td>
                </tr>
            </table>
            <SharePoint:AttachmentUpload runat="server"/>
        </Template>
    </SharePoint:RenderingTemplate>
