Template:Infobox drug

To add multiple parameters at once to the Templatedata section of the Infobox drug template, you can use a JSON array to list all the parameters. Here's an example of how you can add multiple parameters at once using a JSON array:

``` {

   "name": "Infobox drug",
   "description": "A template used to display information about medications.",
   "templateData": {
       "parameters": [
           {"name": "drug_name", "description": "The name of the drug.", "type": "string", "required": true},

           {"name": "DrugBank", "description": "The DrugBank ID for the drug.", "type": "string", "required": false},
           {"name": "ChemSpiderID", "description": "The ChemSpider ID for the drug.", "type": "string", "required": false},
           {"name": "UNII", "description": "The Unique Ingredient Identifier for the drug.", "type": "string", "required": false},
           {"name": "KEGG", "description": "The KEGG ID for the drug.", "type": "string", "required": false},
           {"name": "ChEBI", "description": "The ChEBI ID for the drug.", "type": "string", "required": false},
           {"name": "ChEMBL", "description": "The ChEMBL ID for the drug.", "type": "string", "required": false},
           {"name": "chemical_formula", "description": "The chemical formula of the drug.", "type": "string", "required": false},
           {"name": "molecular_weight", "description": "The molecular weight of the drug.", "type": "string", "required": false},
           {"name": "smiles", "description": "The SMILES notation for the drug.", "type": "string", "required": false},
           {"name": "InChI", "description": "The InChI identifier for the drug.", "type": "string", "required": false},
           {"name": "InChIKey", "description": "The InChIKey identifier for the drug.", "type": "string", "required": false}
       ]
   }

} ```

In this example, each parameter is listed as a JSON object within the "parameters" array, with the "name", "description", "type", and "required" fields specified for each parameter.

Once you've added this JSON array to the Templatedata section of the Infobox drug template, you can save the changes and preview the template to see how the new parameters are displayed.
