 The field source is a property that you can set for some field types in a data template, such as Droplink, Droptree, Multilist, Image, File, and so on. The field source specifies the location of the items or media that the user can select from when editing the field. For example, if you have a Droplink field that allows the user to choose a category for an item, you can set the field source to point to a folder that contains the category items.This way, the user will only see the relevant items in the drop-down list. The field source can be a path, a GUID, or a Sitecore query that returns a single item or a list of items. The field source helps you to control the data source and the user interface for the field. References:

This answer is based on the Sitecore documentation of dynamic placeholders1. Dynamic placeholders are an extension of the regular Sitecore placeholders that allow you to add the same placeholder name several times across multiple renderings, and even within the same rendering. Dynamic placeholders generate a unique key for each placeholder instance, which ensures that the content within the placeholder is unique and not duplicated. Dynamic placeholders also enable you to build functionality that generates multiple placeholders within the same rendering dynamically. For example, you can use dynamic placeholders to create a tab component that can have any number of tabs, each with its own content. References:

The field helper is a Sitecore MVC helper that renders the content of a field in the view. It also enables the field to be editable in the Experience Editor or Horizon. To prevent a field from being edited, you can set the editable parameter to “false” in the field helper. For example, @Html.Sitecore().Field(“title”, new { editable = false }) will render the title field without the editing capabilities. This parameter overrides the default behavior of the field helper, which is to render the field as editable if the page is in edit mode. Setting the editable parameter to “false” can be useful for fields that are not meant to be changed by the content authors, such as system fields or fields that are populated by code.
