Tablet as Item

If you want the tablet to work as an item, you need to create the item based on the inventory script you're using.

ox_inventory

File Location: ox_inventory/data/items.lua

Image Should Be placed in: ox_inventory/web/images

['crime_tablet'] = {
    label = 'Crime Tablet',
    weight = 1,
    type = 'item',
    image = 'tablet.png', -- Optional, if you want an image for it
    useable = true,
    description = 'A tablet for various crime-related tasks.',
    client = {
	event = 'op-crime:openCrimeTablet'
    }
}

qb-inventory

File Location: qb-core/shared/items.lua

Image Should Be placed in: qb-inventory/html/images

crime_tablet = { 
    name = 'crime_tablet', 
    label = 'Crime Tablet', 
    weight = 1, 
    type = 'item', 
    image = 'tablet.png', -- Optional, if you want an image for it
    useable = true, 
    shouldClose = true, 
    description = 'A tablet for various crime-related tasks.' 
},

Basic ESX

This is MySql insert.

INSERT INTO `items`(`name`, `label`, `weight`, `rare`, `can_remove`) VALUES ("crime_tablet", "Crime Tablet", 1, 0, 1)
