Why is menu not showing in Magento admin?

Question

Magento

I create a menu in the magento admin panel, after which only the Header of the page starts showing for me. There are no errors in the logs.

<admin>
        <routers>
            <tseapi_admin>
                <use>admin</use>
                <args>
                    <module>TS_Eapi</module>
                    <frontName>eapiadmin</frontName>
                </args>
            </tseapi_admin>
        </routers>
    </admin>
    <adminhtml>
        <menu>
            <eapiadmin module="eapiadmin">
            <title>admin</title>
            <sort_order>77</sort_order>
                <children>
                    <article module="eapiadmin">
                        <title>Manage Articles</title>
                        <sort_order>70</sort_order>
                        <action>tseapi_admin/adminhtml_eapi</action>
                    </article>
                </children>
            </eapiadmin>
        </menu>
    </adminhtml>

Answer 1

Write the menu settings in the adminhtml.xml file of your module.
Consider app/code/core/Mage/Cms/etc/adminhtml.xml as an example

Answer 2

It is better to create a config taking into account the following recommendations

Since it will not work on sites with the SUPEE-6788 patch or Magento version >=1.9.2.2
