# `MishkaCmsCoreWeb.Live.Admin.Components.ContentMediaChooser`
[🔗](https://github.com/mishka-group/mishka_cms_core/blob/v0.0.1/lib/mishka_cms_core_web/live/admin/components/content_media_chooser.ex#L5)

Media Manager inside the content editor's settings
(`MishkaCmsCoreWeb.Live.Admin.Components.ContentComponentPicker`): the pictures, or the videos,
of the site the record is on, newest first, 48 at a time with Load more for the next, searchable
by name, and an upload that adds a file to the site's media and picks it. At the top, All media,
every folder's files are listed and the folders beside them; a folder opened lists only its own,
and the folders inside it, with the way back up above.

A pick goes back to the settings that opened this as
`send_update(ContentComponentPicker, id: target, media: %{url: url})`, and Back as
`media: :closed` — or to the component `notify` names, a form's picture field
(`MishkaCmsCoreWeb.Live.Admin.Components.MediaField`). The library is read as the signed-in user —
a master's on the record's site, a site user's on their own — and an upload is the `Media`
resource's own `upload` (or `master_upload`) action, so its checks are the library's.

Given a `folder` name, an upload is filed in the folder of that name at the top of the site's
media, made on the first upload; without one, at the top. The author may file it elsewhere — any
folder of the site, none, or a new one made there and then. `library: :closed` shows the upload
alone, and the files only once they are asked for; `back: false` leaves out Back; `in_form: true`
is for a chooser drawn inside another form, whose upload and folder controls must not be a form
inside it. `opened` is the count of the form it is drawn in (`MishkaGervaz.Form.Web.State`): when
it changes, the chooser starts over, closed again as its opener asks.

It is its own component because it reads its own query, in the background.
