index (0, <Property: Electrical>)
index (1, <Property: Environment>)
index (2, <Property: Mass composition>)
index (3, <Property: Mechanical>)
index (4, <Property: Optical>)
index (5, <Property: Thermal>)
index (0, <Physic: ------Electrical Property------>)
index (1, <Physic: Electrical Resistivity (Ohms.cm)>)
index (2, <Physic: ------Environment Property------>)
index (3, <Physic: Energy primary production (J.kg-1)>)
index (4, <Physic: CO2 primary production (kg.CO2.kg-1)>)
index (5, <Physic: ----Mass composition Property---->)
index (6, <Physic: Al (% massique)>)
index (7, <Physic: ------Mecanical Property------>)
index (8, <Physic: Vickers Hardness (GPa)>)
index (9, <Physic: Elasticity Modulus (GPa)>)
index (10, <Physic: Young Modulus (GPa)>)
index (11, <Physic: Shear Modulus (GPa)>)
index (12, <Physic: Maximum Stress (GPa)>)
index (13, <Physic: ------Optical Property------>)
index (14, <Physic: Refractive Index>)
index (15, <Physic: Emissivity (-)>)
index (16, <Physic: ------Thermal Property------>)
index (17, <Physic: Thermal Conduct (W.m-1.K-1)>)
index (18, <Physic: Thermal diffusivity (m2.s-1)>)
I just want each category is associated has a property
a pre-Chosen dropdown on 'Mechanical' has an associated pre-Chosen dropdown
on vickers hardness and Aunsi on
13 or drop-down lists for categories and 13 for properties
how to do ??
