Zabbix module to hide widget headers in view mode Zabbix module that removes widget title bars while dashboards are viewed and restores them automatically when a dashboard is switched to edit mode. It affects only widgets already marked as hidden-header, is implemented as a stylesheet-only module with no server-side component, and provides no user-configurable options. Install on frontend nodes when you want cleaner NOC or wall-display dashboards while keeping widgets fully configurable during editing.

Install via your OS package manager. Using the initMAX repository (apt / dnf / zypper) is the recommended way - you get GPG-signed updates automatically.
wget https://repo.initmax.com/zabbix/release/initmax-release-latest_all.deb
dpkg -i initmax-release-latest_all.deb
apt update && apt install zabbix-module-hidewidgetheaderrpm -Uvh https://repo.initmax.com/zabbix/release/initmax-release-latest.noarch.rpm
dnf clean all && dnf install -y zabbix-module-hidewidgetheaderrpm -Uvh https://repo.initmax.com/zabbix/release/initmax-release-latest.noarch.rpm
zypper --gpg-auto-import-keys refresh && zypper install -y zabbix-module-hidewidgetheaderPaste the block after FROM in the final Zabbix frontend stage.

The block installs the newest available version when the installation step runs. Docker may reuse a cached layer. To keep a fixed version, use zabbix-module-hidewidgetheader=2.2.1_p1-r3
Run the command in a terminal in the Dockerfile directory.
# initMAX hidewidgetheader - Alpine (apk) package install
docker build -t zabbix-web-custom .In Compose, use image zabbix-web-custom and recreate the frontend. In Zabbix, open Administration / General / Modules, Scan directory and enable the module.
No manual APK downloads or file copying.
Buying another product later? Add its install block to the same Dockerfile; keep the existing blocks and products.
For Ubuntu / Debian frontend images. Add after FROM. Keep installed modules in the image; a volume over modules/ would hide package updates.

ZIP modules in a persistent volume. You manage updates manually.
Save the ZIP for your version and edition as module.zip on the Docker host. Unzip it into a new directory as shown below, then read the included INSTALL.md.
WORKDIR=$(mktemp -d)
unzip module.zip -d "$WORKDIR" && cd "$WORKDIR/hidewidgetheader"Keep your existing modules volume. For a new one, merge this Zabbix 8.0 example into Compose and recreate the frontend. Preserve other settings and transfer existing modules before switching. For images with a ui/ directory, mount /usr/share/zabbix/ui/modules. Do not share a volume between different Zabbix versions.
services:
zabbix-web:
volumes:
- zabbix-web-modules-8.0:/usr/share/zabbix/modules
volumes:
zabbix-web-modules-8.0:docker compose up -d --no-deps zabbix-web
Replace zabbix-web with your actual frontend container name. Select legacy/ for Zabbix 6.0–6.2, otherwise modern/.
When updating, back up this module and its settings first. Only its own directory is replaced, never the whole modules/ directory.

Manual copying does not run package pre/post-install or upgrade scripts. If required, follow INSTALL.md. After changing the Zabbix version, use a separate volume with compatible modules and scan again.
